PANEL SEALING
Except for dia. 4 mm shaft, an O.ring is supplied with the
potentiometer. This O.ring should be placed into the groove
of the body and ensures the panel sealing.
For dia. 4mm shaft please see note “P” in ordering informa-
tion.
SHAFTS
Shaft lengths are measured from the mounting face to the
free end of the shaft. Special shafts are available if the
customer supplies a drawing. The shaft slot is aligned to
the wiper within ± 10°.

HARDWARE
Nuts, washer and O.ring are
separately supplied
(not
mounted on the potentiometer), in a small bag placed in
the packaging.
LOCATING PEG
Except for dia. 4 mm shaft, the potentiometers are delivered
with 2 opposite locating pegs orientated at 45°. These
2 pegs can be easily broken-off by the customer.
On request, the orientation of the pegs can be at 30° instead
of 45°. Order Designation : PRV6 L (see ordering information).

“LC” OPTION LOW CURRENT
For sensitive applications, when the current going through the wiper of the potentiometer is very low (less than 1µ Amp) or when
the climatic conditions of use are tightened up, we recommend to use the Low Current (LC) option of the PRV6 and PARV6 series.
The general characteristics of this model are identical with the standard PRV6/PARV6 characteristics but it gives
exceptional results in matter of stability when used in extreme climatic conditions and/or current close to O Amp.
